if you want to make 350- 400 on an NA k20 you better buy some mega million lottery tickets and find a donor k24 bottom end and a type s head along with some expensive$$$ high comp pistons and have some crazy head work done. Swapping a k20 is hard enough especially into a del. But the e85 is totally uneccesary no one has agreed with it yet in this thread and the hp you are asking for is going to be a lot to make out of a dd all motor del. your best bet if you want to be different is swap it with your k24/20 and try to set a 300hp goal. you will have fun with 300whp trust me
